WHEEL FOR ROAD-VEHICLES.

SPECIFICATION forming part of Letters Patent No. 646,028, dated March2'7, 1900. Application fil d December 26,1899. Serial No. 741,632. (Nomodel.)

T0 at whom it may concern:

Be it known that I, J ARRATT LIVERSIDGE, residing at 196 Old street,London, England, have invented certain Improvements in Wheels forRoad-Vehicles; and I do hereby declare the following to be a full,clear, and

exact description of the invention, such as.

Will enable others skilled in the art to which it appertains to make anduse the same.

My improvements consist in forming that part called the stock, nave, orhub of Wheels for road-vehicles with a built up wooden center, theobjects I have in view being as follows:

First. To enable a new spoke or spokes to be driven into the stock orremoved therefrom without disturbing the other component parts thereof.

Second. By means of the particular form of segments and the spokes toform practically a solid Wooden center.

Third. By means of the flange-plates,which are fastened by'bolts orrivets passing through the segments, the full section and strength ofthe spokes are preserved and the component parts of the hub are rigidlyheld together. The horizontal portion of the metal flangeplates istapered and fitted with wood when any ordinary form of axle-box isemployed. The usual forms of metal hub, flange, or flange and hubcombined, or metal hub and box combined, or metal flange and boxcombined can be used, so long as part of any one of the above forms thenecessary flange to cover the feet of the spokes and the wedging of thespokes and segments is not interfered with.

Fourth. A fewer number of spokes can be employed than in wheels whosecenters are composed of spokes only, thus lightening the wheel.

The particular construction by means of which I attain these objectswill be readily understood by means of the accompanying drawings, inwhich Figure 1 is a front elevation of the wheel with flange-plateremoved. Fig. 2 is a perspective view of segment. Fig. 3 is aperspective view of spoke. Fig. 4 is a sectional plan on line A B,Fig. 1. Fig. 5 is a section of flange-plates.

Similar figures refer to similar parts in all the Views.

1 is one of the double wedge-shaped segments, which is grooved orrecessed on either side of each shoulder, as at 2, and bored for thebolt, as at 3. The exterior of each segment is slightly rounded, as at4, so as to preserve the external contour of the stock or nave 5.

Fig. 3 shows a spoke. This is turned or otherwise tooled to the usualrounded or other shape 6 at its outer end, so as to fit a correspondinghole or mortise 6 in the folly. The inner end of each spoke iswedge-shaped, as at 7, on either side, the taper being the same asthatformed upon the outer part of each segment, as at 7 and at the foot Imay form a cross-tenon 2, which exactly fits the halfmortise or recess 2formed on either side of each segment. Each flange-plate 8, which isusually a casting in malleable iron, gun-metal, steel, or other suitablemetal, or may be stamped, welded up, or otherwise formed, is drilledwith a series of holes 3, so as to exactly correspond with those formedin the segments, the horizontal portion of each plate being tapered, asat 8, and filled in with wood 9.

The wheel is built up as follows: A series of segments and spokes areranged in order. The rounded or other-shaped end of each spoke is nextinserted in the corresponding hole formed in the felly, the whole ofwhich, as well as the spokes, are then forced inward by pressure. Theplates are then bolted, as at 10, or riveted on.

If the wheel is to be built with straight spokes, the flanges of bothplates will be square with their horizontal axis. ever, the spokes areto be dished, the flange of the outer plate 11 is beveled, as at 8", tothe dish of the spoke, and that part of the segment against which theflange-plate comes is shaped so as to be flush with the spoke, thehinder portion or foot of spoke being cut to bevel of dish.

It will be seen that by means of my invention an old spoke can be takenout and'replaced, as in the case of an ordinary wheel, without, however,destroying the solidarity of the hub. Moreover, as the segmentaltapering is radial it follows that the central portion of the nave,stock, or hub, although built up in the manner described, is wedged If,howby the pressure so tightly together as to form practically a solidwooden center. For a similar reason it is obvious that the spokes arefirmly keyed in position; but as no bolt passes through them thestrength of their whole section is secured.

In some cases I may dispense with the crosstenon 2, leaving the foot ofspoke plain and omitting the recess 2 in the segment.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In a wheel for road-vehicles the combination of a hub formed ofdouble wedgeshaped segments having their lower Wedgeshaped halvescontiguous to each other,spokes adapted to fit in the spaces between theupper wedge-shaped halves of said segments and flange plates securingsaid segments and spokes together, substantially as set forth.

2. In a wheel for road-vehicles the combination of a hub formed ofdouble wedgeshaped segments having their lower halves contiguous andprovided with recesses in their shoulders adapted to come opposite eachother thus forming larger recesses at the bottoms of the spaces betweenthe upper halves of said segments, spokes adapted to fit into saidspaces and providedwith cross-tenons at their feet which fit into saidrecesses, flange-plates securing said segments and spokes together, andbolts or rivets passing through said flangeplates andsegments,substantially as set forth.

3. In a Wheel for road-vehicles the combination of a hub built up ofsegments, dished spokes fitted into said hub, flange-plates securingsaid spokes and hub together and beveled to correspond to the dish ofsaid spokes, substantially as set forth.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
